Keyes WS2812 is a intelligent control LED light source that the control circuit and RGB chip are integrated in a 5050 SMD component. It includes intelligent digital
portdata latch and signal reshaping amplification drive circuit. Also includes a precision internal oscillator and a 12V programmable constant current control part,
effectively ensuring the highly consistency of the pixel point light color.
The data transfer protocol uses single NZR communication mode. After the pixel power-on reset, the DIN port receives data from controller, the first pixel collect
initial 24 bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit are sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal reduces 24 bit. Pixel adopts auto reshaping transmit technology, making the pixel cascade number not limited by the signal transmission, depending only on the speed of signal
transmission.
LED with advantages of low driving voltage, environmental-friendly, energy saving high brightness, large scattering angle, good consistency, long life span etc.
